DOORQCHCK.

SPECIFICATION forming part of Letters Patent No. 350,887, dated October 9, 1888.

Serial No. 280,737.

(No model.)

To @ZZ whom it may concern:

Be it known that I, SYLVESTER HUGH MILES, a citizen of the United States, residing at Rossville, county of Shawnee, and State of Kansas, have invented certain new and useful Improvements in Door Stops, of which the fol` lowing is a specification.

y invention relates to a device which is adapted to he arranged in connection with a door, and so attached as to be operable by the door knob, the other end being provided with a moving latch suitably pivoted, which latch is adapted to catch or slip into a semicircular securing-plate placed upon the jamb or doorframe.

My particular invention consists in a simplification ofthe Various parts and the specific arrangementshown in the drawings, and pointed out in the claim.

Referring to the accompanying drawings, which form a part of the specilication, Figure l is an elevation showing a door With my attachment applied. Fig. 2 is a. detail perspective view ofthe said attachment.

In the drawings, A represents a door proihe shank C of the door-knob is provided with a disk, D, having two small pins, E, upon one of the faces. These small pins extend outwardly and are raised in the same horizontal plane and on the same side of the disk.

A yoke or Y-shaped lever, F, straddles the door-knob, the two branches of the yoke eX- tending downwardly and in proximity to the disk D. The branches ofthe yoke are provided with semicireular slots, and the yokeshaped lever and disk are so arranged in regard to each other that the pins on the disk willextend th rough theslots on thelever,so that by working the door-knob either to the right or to the left the disk, which rotates therewith, will cause the yoke to be drawn down by virtue otl one or the other ofthe pins engaging in the bottom of its corresponding` slot. The upper part of the yoke or lever F is provided with two downwardly-extending Iingers,G,between which is placed a rod, H, arranged to move slightly between the two fingers. This rod H is set vertically, and is attached at its upper end to a bell-crank lever, J, which is pivoted to the door by means of the bolt K. end of the bell-crank lever is swiveled to a horizontallymoving rod, L, which turns on and is pivoted at its upper end to the latchlever N. The upper end of the latch-leverNis adapted to engage in the serrations or openings provided inthe outer edge or periphery of the securing plate M. This semicircularsecuring-plato is attached to the doorjamb or frame, and as the door is swung around the knob, being controlled by the hand, can be held down until the door is opened into the desired position, when the knob can be liberated and the locking lever slipped into one of the openings or serrations of the securing-plate.

In connection with the various joints of the apparatus I arrange boxes R for covering the same, having in the sides thereof slots for the accommodation of the levers working therethrough. The advantage of this is that the working parts are always kept clean and free from dust and are removable from said box, both of which are great advantages, and both of which are found desirable.

A spring, S, is provided for withdrawing the levers and knob automatically to their normal positions if there happens to be any tension in the apparatus. By placing the yokeshaped lever as shown and described it is hidden from view by the inclosingcase and bythe door-knob, and thus the construction is desirable in this respect.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

Thecombination of a door-handle, a disk,
